modules/recon/private-key-exposure.yaml flags an exposed PEM private key on the BEGIN PRIVATE KEY marker, so a public key or prose that merely names a key is left alone, then extracts the key type. modules/recon/git-credentials-exposure.yaml flags an exposed git credential store on a remote url that carries an inline password, paired with a guard that drops a url shown inside an html page, then extracts the host the credential reaches. modules/recon/pypirc-exposure.yaml flags an exposed pypirc on an index section paired with a credential field, then extracts the pypi upload token. requiring the credential keeps a bare index listing from being reported. internal/modules/secret_file_exposure_test.go drives the three modules end to end through ExecuteHTTPModule and asserts the leak alongside the near misses a strict review wants pinned: a public key, prose that names a key, a remote url with no password, a pypi section with no credential, a credential shown in an html page, a plain 200 body and a 404, none of which may match. verify: go test ./internal/modules, each matcher, marker, guard and extractor proven to bite (break -> red, restore -> green).
